Thawing sea ice may have opened the door, allowing the infection to cross oceans, a new study suggests.

Aerial surveys this September and October show the bowheads aren’t where they usually are.

Gradual sea ice reduction and reconfiguration of the coast, have increased the rate of erosion near Port Heiden over the course of several decades. Draining of Goldfish Lake brings memories, loss of community landmark, and many emotions.

This year was one of the warmest and wettest in recorded history and permafrost thaw is causing the ground at the community cemetary to thaw and erode. The community is seeking guidance on best practices for relocation of remains.

This stoop-pumpkin-rotting event is unusual compared with Dr. Johnson's long-term (lifetime) time series of annual October observations of stoop pumpkins in New York City.

Nils Thomas discovered "sinkhole" in the middle of Finnmarksvidda. Scientists have long warned against this, and now it happened.

Instead of halibut, fisherman are increasingly catching less valuable Pacific cod, voracious bottom feeders whose numbers in recent years have exploded.

The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."

While there is no risk to human health, the species of moth can decimate forests

Thousands of smelts were found dead during low tide in the Togiak slough. Is there an environmental cause?

Anglers in Aklavik, N.W.T., are trying to figure out why there was a shortage of fish in local hotspots this year.

The death toll in the Camp fire in Northern California rose to 63 Thursday as President Trump planned to visit California to meet with people impacted by the wildfires in what marks his second trip to the state since his election.

The skin lesion in the photo is likely caused by a stress-related bacterial infection – possibly trauma initiated. Probably common opportunistic bacteria in the environment such as motile Pseudomonas/Aeromonas Gram-negative organisms.

Odd time of year for seals to be eating herring.

The two whales were spotted just 10 minutes outside of Pond Inlet, surprising local guides and scientists, who say it's a sign of shifts in the ecosystem.

Many mature Sitka spruce trees dying off from French Beach south into Sooke along waterfront. Many dead partway up and needles thin.

For 300 years, glacial runoff was the major water source for Kluane Lake, flowing in by way of the Slims River. But in May 2016, Kluane Lake levels dropped precipitously. The problem was a case of "river piracy" — incredibly rare, and hugely significant. The terminus or end of the Kaskawulsh glacier had receded enough that a glacial lake that fed the Slims River suddenly drained when the glacier outflow found a new direction to a new river.

Squid are becoming more common on the shoreline over the past few years.
